3 Claims.

'I'his invention relates generally to internal combustion engines and has particular reference to engines of the horizontal type and the invention relates more specifically to a cooling arrangement for the cylinders of such engines.

' One object of this invention is the provision of an internal combustion engine of the horizontal type in which a water jacket is provided entirely around each of the several cylinders thereof.

This application is a division of application filed October 21, 1933, Serial No. 694,552, Internal combustion engine.

Other objects and advantages of this invention will lbe apparent from the following description taken in Yconjunction with the accompanying drawings in which:

Figure 1 is a view in transverse vertical section of an engine embodying the present invention;

Fig. 2 is an enlarged ydetail View, in section, through a portion of the cylinder block at its forward end, the view also showing a portion of the cylinder head and manifold associated there- With, and

Fig. 3 is a sectional view on the line 3 3, Fig. 2.

Referring now more particularly to the drawings in which similar characters of reference designate similar parts in the several views, the drawings show an engine of the horizontal type comprising a cylinder block 2 and a crank case Il. In the instance shown the crank case and cylinder block are formed as a unitary casting but obviously this is merely by Way of example as they may be independently cast elements suitably connected together. The engine also includes a cylinder head E, see Fig. 2, said figure showing only a portion thereof but suflicient to disclose a water jacket as more clearly described hereinafter.

The engine is provided with a plurality of cylinder sleeves 3 Which are fitted within the cylinder block in such a manner as to provide a separate water jacket l0 around each of the sleeves 8. As shown clearly in Fig. 1, the rear end portion of each cylinder sleeve 8 is enlarged tted in a circular recess formed in an inturned annular ange i3 at the forward end of the cylinder block. The construction just described obviously provides for spacing the walls of the 55 cylinder block from the sleeves 8 whereby to provide independently functioning separate water I jackets i3 for the cylinders of the engine.

As shown in Fig. 2, a water intake manifold indicated generally at M is formed with the lower Y wall 22 of the cylinder block adjacent the forward end portion thereof and is provided with a water 15 intake pipe P fastened thereto in any suitable manner as by the bolts 2E. The manifold M eX- tends substantially the full length of the cylinder block 2 and, adjacent each water jacket lil, a port 28 is provided to permit passage of water 20 from the manifold to each of sai-d water jackets.

The cylinder head 6 is connected to the cylinder block 2 in any suitable manner and is so formed as to provide a water jacket Sii which receives water from the jackets i@ through registering

ports

32 and 34 formed in the cylinder block 2 and cylinder head respectively. As clearly shown in Fig. 2,

ports

32 and 34 are formed both in the upper and lower portions of the cylinder block and cylinder head respectively. There are separate ports for each of the several cylinders of the engine which feed into the water jacket 3i? of the cylinder head 6.

Secured to the cylinder head 6, as clearly shown in Fig. 2, is an intake manifold B which com- 35 prises preferably a casting having a conduit 36 for fuel and a passage 38 connected with the water jacket 3D of the cylinder head 6; the passage 38 leading to a water return line i2 connected to the manifold B by suitable fasteners such as the 40 bolts 42. In practice, and as mentioned in copending application, Serial No. 694,552, of which this application is a division, the intake manifold casting will be provided with a plurality of passages 38 each leading to and connected with a 45 Water return line 4i).

From the description just above it can be seen that the present invention provides an internal combustion engine of the horizontal type having a plurality of cylinders, each of which is completely surrounded by a water jacket whereby water completely encircles each of the cylinders. Still further, it can be seen that the water inlet is arranged at the lower part of the cylinders whereby the water enters the cylinder block from below and, as it becomes heated, passes upwardly and into the cylinder head and finally, through the passages 38 of the intake manifold B, to the return line 40. Withi this arrangement the possibility of the formation of steam pockets in the water jacket is efectually eliminated.

The drawings illustrate one embodiment of the present invention but it is to be understood that they are for illustrative purposes only and Various changes in the form and proportions of the construction may be made within the scope of the appended claims without departing from the spirit of the invention.

What is claimed is:

1. In an internal combustion engine having an an inlet, a crank case, a cylinder block extending therefrom in a substantially horizontal plane, a cylinder sleeve in said block having its end portions in sealing engagement with the cylinder block and its intermediate portion spaced from the cylinder block to provide a water jacket eX- tending completely around the cylinder sleeve between the end portions, means for admitting water into the lower portion of said water jacket, a cylinder head secured to the forward end portion of the cylinder block and formed to include a water jacket, ports connecting the water jacket of the cylinder block with the water jacket of the cylinder head, and means for discharging the warm water from the cylinder head at its upper portion and transferring partv of its heat to the inlet gases. Y

2. In an internal combustion engine, a crank case, a cylinder block extending therefrom in a substantially horizontally plane, a cylinder sleeve in said block having its end portions in sealing engagement with the cylinder block and its intermediate portion spaced from the cylinder block to provide a water jacket extending completely around the cylinder sleeve between the 5 end portions, means for admitting water into the lower portion of said water jacket, a cylinder head secured to the forward end portion of the cylinder block and formed to include a water jacket, ports connecting the water jacket of the cylinder block with the water jacket of the cylinder head, and an intake manifold secured to the cylinder head and formed to provide receiving portions for water from the cylinder head water jacket.

3. In an internal combustion engine, a crank case, a cylinder block extending therefrom in a substantially horizontal plane, a cylinder sleeve in said block having its end portions in sealing engagement with the. cylinder block and its inter- 20 mediate portion spaced from the cylinder block to provide a water jacket extending completely around the cylinder sleeve between the end portions, means for admitting water into the lower portion of said water jacket, a cylinder head se- 25 cured to the forward end portion of the cylinder block and formed to include a water jacket, ports connecting the water jacket of the cylinder block with the water jacket of the cylinder head, and an intake manifold secured to the upper surface of the cylinder head and formed to provide receiving portions for water from the cylinder head water jacket.
